6. A CAR RETARDER CONTROL SYSTEM FOR A MASTER RETARDER LOCATED BETWEEN A HUMP AND AT LEAST ONE GROUP RETARDER, COMPRISING, IN COMBINATION, MEASURING MEANS FOR DERIVING SIGNALS IN ACCORDANCE WITH THE SPEEDS OF CARS APPROACHING THE MASTER RETARDER, COMPUTING MEANS ADJUSTED IN ACCORDANCE WITH THE PREDETERMINED PERFORMANCE OF CARS OF MAXIMUM AND MINIMUM ROLLING RESISTANCE IN SAID MASTER RETARDER WHEN SAID MAXIMUM ROLLING RESISTANCE CAR IS NOT RETARDED AND SAID MINIMUM ROLLING RESISTANCE CAR IS RETARDED SUFFICIENTLY TO TRAVEL FROM THE HUMP TO A SELECTED POINT AT THE GROUP RETARDED IN THE SAME TIME INTERVAL AS THE MAXIMUM ROLLING RESISTANCE CAR, SAID COMPUTING MEANS CONTROLLED BY SAID SPEED SIGNALS FOR COMPUTING THE SPEED AT WHICH EACH CAR SHOULD LEAVE THE MASTER RETARDED IN ORDER TO TRAVEL BETWEEN THE HUMP AND SAID SELECTED POINT IN THE SAME INTERVAL AS THE MAXIMUM ROLLING RESISTANCE CAR, AND MEANS CONTROLLED BY SAID COMPUTING MEANS FOR ACTUATING THE MASTER RETARDER TO REDUCE THE SPEED OF EACH CAR TO ITS COMPUTED LEAVING SPEED.
